Patent CA-2235097-A1 (CA)
Inventor: RYAN JOHN O
IPC: H04N7/167
Filed: 1992-11-12
Abstract: L'invention est un système de brouillage vidéo qui produit une fluctuation aléatoire, par exemple un décalage temporel, de la position de la partie active d'une trame vidéo sans perturber le signal de synchronisation horizontale et la salve couleur dans chaque ligne vidéo, ce qui en fait un système de protection et de camouflage. On accentue la protection en remplissant l'intervalle entre le début nominal de la partie active de la trame vidéo et le début réel de celle-ci par un signal vidéo synthétisé qui reproduit la partie active adjacente de la trame vidéo au moyen d'une configuration de remplissage engendrée numériquement. De plus, l'emplacement de cet intervalle est camouflé au moyen d'un bruit aléatoire superposé. On accentue le camouflage en produisant une fluctuation temporelle du signal de synchronisation horizontale au moyen d'une ou deux fréquences et en modifiant de façon aléatoire la position du signal de synchronisation verticale. Le codage numérique NTSC de l'invention est simplifié par l'utilisation de deux canaux seulement,  le canal de chrominance et le canal de luminance, et par l'utilisation d'un circuit hétérodyne pour stabiliser la chrominance. On accentue ce codage en fournissant, au moyen du canal de chrominance, des détails qui sont perdus normalement. De plus, un signal vidéo non standard peut être incorporé a une partie de la salve couleur du palier avant de la suppression de ligne, ce qui permet d'utiliser un décodeur relativement simple.

Filed: 1998-05-15
Abstract: Il est d'usage courant de regrouper plusieurs publicités à l'intérieure d'enveloppes ou de sacs afin de les distribuer de porte en porte. La présente invention est un objet original conçu spécialement pour rassembler, pour des fins de distribution publicitaire, des cartes d'affaires que le destinataire pourra conserver afin de les consulter en tout temps. Contrairement aux enveloppes et aux sacs, la particulatité de la présente invention est d'être munie, dans la partie supérieure, d'une ouverture formant un crochet qui permet de suspendre l'objet à tous les endroits où il doit être distribué et ,dans la partie inférieure, d'une pochette pour contenir les cartes. Étant donné son petit format, il est important que cet objet distribué de porte en porte soit suspendu afin d'être visible et facilement accessible. Contrairement aux sacs et aux enveloppes, la présente invention est suffisamment rigide pour être suspendue par une ouverture formant un crochet et pour fournir un support utile et durable pour les cartes qu'il contient, résistant ainsi aux manipulations que pourra en faire l'usager sans se déchirer ni se froisser. La pochette ouverte de la présente invention permet une grande économie de moyens autant lors de sa conception que lors de l'insertion des cartes en vue de la préparation de la distribution. La pochette facilite également l'accès au contenu pour le destinataire, lequel pourra de plus conserver l'objet comme un accessoire de rangement utile, permettant une consultation rapide, pratique et agréable des cartes qui y sont insérées. Cette invention porte par ailleurs un trait poinçonné permettant de détacher la partie supérieure formant un crochet de la partie inférieure formant la pochette renfermant les cartes, permettant ainsi au destinataire de ne conserver que la pochette, qui est plus petite, si tel est son désir. Si seule la pochette est conservée, il devient plus facile de la manipuler et de la transporter dans la poche d'un vêtement. Grâce à la conception suffisamment rigide de la pochette, les cartes qui y sont insérées sont protégées et tiennent bien en place sans que la pochette n'ait à être refermée.

Patent CA-2235887-A1 (CA)
Title: Painting system including a desiccant dehumidifier for conditioning air recirculated to a spray paint booth
Inventor: FLYNN PAUL JEFFREY
IPC: B05B15/12
Filed: 1998-05-26
Abstract: A painting system includes a paint spray booth ventilated by process air including a combination of outside make-up air and a portion of the exiting process air which is returned to the booth, the returned air being the main component of the combination. The humidity of the air in the paint spray booth is controlled by routing a first minor portion of the process air exiting the booth through a desiccant dehumidifier, which removes moisture and volatile organic compounds (VOCs) from this process air portion before it is sent back to the paint spray booth. The dehumidifier is designed so that at any given time the process air portion contacts only part of the desiccant bed while air heated to approximately 250° F. in a paint cure oven is exhausted from the oven and directed through the remaining part of the desiccant bed in order to dry, and thus generate, the desiccant for continued use. The dehumidifier is designed so that a continual exchange of dried desiccant for moisture laden desiccant respectively takes place relative to the process and heated air streams. The heated air also removes a large portion of the VOCs from the first minor portion of the process air. A second minor portion of the process air exiting from the paint spray booth, equal to the volume of make-up air, and the heated regenerative air exiting the dehumidifier are routed through a control device, such as a thermal oxidizer, which destroys the VOCs contained in this air before exhausting it to the atmosphere.

Title: Electrochemical oxidation of hydrogen sulfide
Inventor: CHUANG KARL T
IPC: H01M8/12
Filed: 1998-10-30
Abstract: The invention relates to a process for gas phase electrochemical oxidation of H2S to sulfur and water or steam using an electrolysis cell having an anode chamber on one side of a solid proton conducting membrane and a cathode chamber on the other side of the membrane. The process comprises the steps of passing H2S-containing gas through the anode chamber to contact a catalytic anode, where it reacts to produce elemental sulfur, protons and electrons. The protons pass through the membrane from the anode chamber to the cathode chamber. An oxygen-containing gas is passed through the cathode chamber to contact the catalytic cathode, where it reacts with protons and electrons to produce water or steam. During the process, both the anode chamber and cathode chamber are maintained at a temperature of at least 120°C and an elevated pressure sufficient to keep the membrane moist.  Sulfur is obtained in liquid or vapour form and is removed from the anode chamber while water or steam is removed from the cathode chamber. An electric current can be withdrawn from the anode and cathode. The cell can also be operated in the electrolysis mode to produce sulfur and hydrogen.

Abstract: The present invention relates to a flow control system for sprayer nozzles.  The control system includes a solenoid coil and a solenoid plunger. The solenoid plunger can slide into an adapter body, substantially perpendicular to the direction of fluid flow. In reducing the fluid flow through the nozzle, the plunger is moved to block an orifice in the path of the fluid flow, within the adapter. The plunger movement is achieved through the energization of the solenoid coil, with signals sent by a controller. The orifice in the adapter is manufactured to a specific size which allows reduced power consumption to shut off or reduce flow through the nozzle. Also, the orifice is sized to provide unrestricted flow when fully open. By means of the controller, control can be provided individually to each nozzle from a plurality of nozzles on a spraying bar. In one aspect of the invention, the flow control system can be used on agricultural sprayers with sensing equipment such as cameras that may determine the green condition of the foliage being sprayed. According to the determined condition, the controller would regulate the flow through the nozzles in the corresponding area of the field.
